JAMES A. STUART, OE GLENDORA, CALIFORNIA.

HINGE.

To all whom it may concern:

Be it known that I, JAMES A. STUART, a citizen of the United States, residing at Glendora, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to improvements in hinges and particularly relates to gravity hinges.

It is an object of the invention to provide a hinge of the gravity type provided with leaf members which may be made as duplicates, a lifting rod being interposed between the leaf members and a guiding pintle being adapted to direct the same.

In the accompanying drawing forming a part of this specification: Figure 1 is a front elevation showing the improved hinge applied to a door or swinging part. Fig. 2 is an end elevation of the said hinge mechanism looking at the same from the bottom. Fig. 3 is an enlarged detail sectional view taken upon the line 33 of Fig. 1.

The details and features of the invention will now be more specifically described, reference being had to the said drawing in which '5 indicates a leaf member adapted to be secured to the swinging part or door and 6 a leaf member adapted to be fastened to the support for the hinge, while 7 indicates a guiding pintle or rod adapted to direct the movement of the leaves and 8 indicates a swinging lifting rod interposed between the said leaf members.

The present invention is an improvement over the hinge structure described and claimed by me in Patent No. 945,820 granted to me January 11, 1910. In the hinge structure made in accordance with the present invention the leaf members 5 and 6 can bemade exactly alike and interchangeable and are preferably formed of flat materials having the ends bent at an angle thereto, thus the inner ends of the leaves are bent to form pintle engaging arms 9 having perforations 10 formed therein through which the end of the stationary pintle or rod 7 is inserted. The base of the said leaves are also perforated for receiving screws by which the leaf members are secured to the swinging member and support as clearly in dicated in the drawing. The outer ends of said members are bent upwardly to the Specification of Letters Patent.

proper angle for forming arms 11. The body portions of said leaf members are set at an angle to the pintle 7 while the ends 9 and 11- are arranged parallel with each other and in horizontal planes. The arms 11 are formed with recesses 12 in their inner surface, usually made by impressing the material of the leaves at that point to form a socket such as is clearly illustrated in Fig. 8, the said recesses being adapted to receive the beveled and pointed ends 13 ofthe lifting rod 8. The pintle 7 is formed with a securing foot portion 14 which is offset and bent to one side of the axis of the pintle so as to receive a securing screw when it is to be fastened into place. The upper end of the said pintle is thus rigidly held in position and the lower end which is inserted in the aperture 10 of the upper arm 9 on the leaf member 6 is also held in fixed posit-ion.

The parts of the structure are such that when the door or movable member is swung outwardly, the lifting rod 8 will force the leaf 5 upwardly along the guiding pintle 7 as indicated in dotted lines in Fig. l. l/Vhen the door is released the action of gravity will cause the parts to assume the position shown in full lines in said Fig. 1 again. The leaves may be readily struck from a single piece of material and may be in duplicates, a pair of leaves being merely turned in opposite directions with respect to each other as shown in Fig. 1 when they are applied to the parts to be connected, in use.

. The pintle 7 can be made .of any ordinary stiff wire and the lifting rod 8 can likewise be made of wire of the desired strength and stiffness. The structure of the present hinge is thus shaped and more easily made than that of the hinge shown and described in my former patent above referred to and its action is fully as effective if not better.

lVhat I claim is:

1. A hinge mechanism, comprising inclined leaf members having horizontal end arms, a fixed pintle mounted separately from said leaf members connecting the adjacent end arms of'said leaf members, and a lifting rod engaging the arms at the opposite outer ends of said leaf members.

2. A hinge mechanism, comprising duplicate leaf members having end arms projecting therefrom, the arm at one end of each leaf member being shorter than the arm at the other, a guiding pintle engaging apertures formed in the short arms, the other have hereunto subscribed myvname this 26th arms havijilg sockets formed therein, and a day of August, 1911. 1 pointed 1i ting rod engaging the recesses in the other arms for lifting one leaf With re- JAMES STUART spect to the other and moving it along the Vitnesses: guiding pintle.
